I believe Neil mentioned that RAID-5/6 always makes a copy, while only RAID-1/10 uses the same page without copying. I get mismatches on RAID-10, but not on the one that has LVM on it, only on the one(s) where the filesystem (ext3) is directly on the RAID volume. bye, -- piergiorgio -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
